Description
Technical Field
[0001] The present application relates to the field of shoe technology, and in particular to a control system capable of adjusting the bending stiffness of a shoe sole. Background Art
[0002] The bending stiffness of the sole is usually a fixed value after the finished product is manufactured. Users have different requirements for the bending stiffness of the sole in different sports states and wearing scenarios. When playing high-intensity basketball games, increasing the bending stiffness of the forefoot of the sole can improve the athletic performance of jumping, changing direction and other actions; during low-intensity training and competition or daily wear, reducing the bending stiffness of the forefoot of the sole can improve wearing comfort. For the same pair of shoes, users have different requirements for the bending stiffness of the sole in different sports states. The sole includes an insole, a midsole and an outsole. The insole provides sweat absorption, reduces sole friction and other functions, the outsole provides anti-slip, wear resistance and other functions, and the midsole is located between the insole and the outsole, providing shock resistance, energy absorption and rebound. The bending stiffness of the sole mainly depends on the bending stiffness of the midsole.
[0003] In response to the above needs, a shoe sole with adjustable bending stiffness is invented, and the bending stiffness of the shoe sole is adjusted by adjusting the relative position of the midsole rigid part and the midsole. Although the invention meets the need to adjust the bending stiffness of the shoe sole, the adjustment method adopts manual adjustment or mechanical switch adjustment, which is cumbersome and not convenient and intelligent enough. Summary of the invention
[0004] The purpose of the present application is to overcome the above-mentioned defects or problems existing in the background technology and to provide an intelligent control system for adjusting the bending stiffness of the sole.
[0005] In order to achieve the above purpose, the following technical solutions are adopted:
[0006] A control system for adjusting the stiffness of a sole comprises a sole and a controller, wherein the sole comprises a midsole body, a sliding member and a driving member, wherein the sliding member is disposed in the midsole body and extends in a front-to-back direction, and the sliding member is driven by the driving member to slide relative to the midsole body in a front-to-back direction to adjust the bending stiffness of the sole; the controller is disposed on the hand and comprises a stretch sensor and a signal generator, wherein the stretch sensor is used to sense the stretching or contraction of finger skin, and controls the driving member through the signal generator to drive the sliding member to slide forward or backward.
[0007] Furthermore, the stretch sensor is a resistive stretch sensor, and its resistance value changes with its stretching or contraction deformation.
[0008] Furthermore, the controller compares the resistance value of the stretch sensor with the stretch threshold and the resistance value of the stretch sensor with the contraction threshold, and controls the driving member according to the comparison result: when the resistance value of the stretch sensor is greater than or equal to the stretch threshold, the signal generator controls the driving member to drive the sliding member to slide forward; when the resistance value of the stretch sensor is less than the contraction threshold, the signal generator controls the driving member to drive the sliding member to slide backward.
[0009] Furthermore, there are several stretch sensors, all used to sense the stretching or contraction of the finger skin.
[0010] Furthermore, the driving member is a motor, and the motor drives the sliding member to slide forward or backward by rotating forward or reversely.
[0011] Furthermore, the midsole body is provided with a slide groove extending along the front-to-back direction, and the sliding member is accommodated in the slide groove.
[0012] Furthermore, the midsole body is provided with a cable, which connects two ends of the sliding member and extends out of the sliding groove to be connected with the driving member. The driving member pulls the cable to drive the sliding member to slide in the sliding groove along the front-rear direction.
[0013] Furthermore, the sliding member is made of carbon fiber.
[0014] Furthermore, the controller is placed on the wearable article, and the stretch sensor is used to sense the stretching or contraction of the wearable article.
[0015] In addition, the present invention also provides a shoe, comprising any of the above-mentioned soles.
[0016] Compared with the prior art, the above solution has the following beneficial effects:
[0017] 1. The sole includes an insole, a midsole and an outsole. The bending stiffness of the sole mainly depends on the bending stiffness of the midsole. A sliding member is arranged in the midsole body, and the sliding member is placed in the midsole body and extends in the front-to-back direction. The sliding member extends in the front-to-back direction. When the sliding member is located at the forefoot portion of the midsole body, the bending of the midsole body will drive the sliding member to bend, thereby increasing the bending stiffness of the sole. The sliding member is driven by a driving member to slide relative to the midsole body in the front-to-back direction. When the sliding member is located at different parts of the midsole body in the front-to-back direction, the bending stiffness of the sole is different. When the sliding member slides forward to the forefoot portion of the midsole body, the bending stiffness of the sole increases; when the sliding member slides backward to the forefoot portion not located in the midsole body, the bending stiffness of the sole decreases. The driving member drives the sliding member to slide in the front-to-back direction, so that the bending stiffness of the sole can be adjusted by the driving member. The controller includes a stretching sensor and a signal generator. The stretching sensor is used to sense the stretching or contraction of the finger skin, and the signal generator controls the driving member to drive the sliding member to slide forward or backward. By sensing the stretching or contraction of the finger skin, the slider is driven to slide forward to increase the bending stiffness of the sole, and slide backward to reduce the bending stiffness of the sole. Previously, the driver was controlled by manual or mechanical switches, but now it is smarter and faster to control it with a stretch sensor.
[0018] 2. The resistance value of the stretch sensor changes with its deformation of stretching or contraction. The stretch sensor is attached to the skin. When the human body moves, the relative position of the skin moves, which drives the stretch sensor to stretch or contract, causing its resistance to change. The stretch sensor senses the movement state of the human body and intelligently adjusts the bending stiffness of the sole to improve the user experience.
[0019] 3. The controller compares the resistance value of the stretch sensor with the stretch threshold and the resistance value of the stretch sensor with the contraction threshold. When the stretch sensor is stretched, its resistance value increases. When its resistance value is greater than the stretch threshold, the controller controls the driving member to drive the sliding member to slide forward to increase the bending stiffness of the sole. When the stretch sensor contracts, its resistance value decreases. When its resistance value is less than the contraction threshold, the controller controls the driving member to drive the sliding member to slide backward to reduce the bending stiffness of the sole. By comparing the resistance value of the stretch sensor with the threshold, the movement state of the human body is intelligently analyzed, and the bending stiffness of the sole is adjusted to suit the movement state, providing an intelligent and personalized adjustment method.
[0020] 4. There are several stretch sensors, all used to sense the stretching or contraction of the finger skin. Using different numbers of stretch sensors can improve the accuracy of adjusting the bending stiffness of the sole. Different trigger gestures can also be set to increase the personalization of the adjustment method. When the resistance values of several stretch sensors are simultaneously greater than the stretch threshold or less than the contraction threshold, the signal generator controls the driver, which can avoid false triggering of the driver and maintain the accuracy of the adjustment.
[0021] 5. The motor rotates forward or reversely, driving the slider to slide forward or backward. The forward rotation of the motor corresponds to one direction of movement of the slider, and the reverse rotation of the motor corresponds to the opposite direction of movement of the slider. Using a motor to drive the slider allows the signal generator to control the motor to produce different rotation directions and adjust the bending stiffness of the sole. Compared with manually driving the slider, it saves manpower and improves the user experience.
[0022] 6. The midsole body is provided with a slide groove extending in the front-to-back direction, and the sliding member is suitable for sliding in the front-to-back direction in the slide groove. The slide groove provides a slideway for the sliding member to slide in the front-to-back direction, so that the sliding member can slide smoothly.
[0023] 7. The cable is fixedly connected to both ends of the sliding member and extends out of the slide slot to connect with the driving member. The driving member drives the cable to drive the sliding member to slide in a forward and backward manner to adjust the bending stiffness of the sole. The driving member drives the sliding member to slide in the forward and backward direction in the slide slot by retracting and releasing the cable. The driving member retracts the cable at the front end of the sliding member, releases the cable at the rear end of the sliding member, drives the sliding member to slide forward, and enhances the bending stiffness of the sole; the driving member retracts the cable at the rear end of the sliding member, releases the cable at the front end of the sliding member, drives the sliding member to slide backward, and reduces the bending stiffness of the sole. Driving the sliding member by the cable reduces production costs and makes the overall operation more stable.
[0024] 8. The sliding part is made of carbon fiber, which has the characteristics of light weight and high rigidity. It can also provide users with boosting performance when the sliding part recovers from deformation.
[0025] 9. The controller is placed on the wearable object. When the human body uses the wearable object, it will stretch or shrink. The stretch sensor is used to sense the stretch or shrinkage of the wearable object and control the drive element through the signal generator. Placing the controller on the wearable object is more comfortable and convenient for users to use the control system than attaching it to the skin surface.
[0026] 10. The shoes manufactured using the above technical solution can control the motor through the controller to intelligently adjust the bending stiffness of the sole. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings.
[0038] See also Figure 1 , Figure 1 A sole of a control system for adjusting the bending stiffness of the sole provided by this embodiment is shown. Figure 2 A controller of a control system for adjusting sole stiffness provided by this embodiment is shown.
[0039] Figure 1 The above-mentioned upward view is a direction identification based on the direction of the sole. The direction of the sole from the part in contact with the ground to the part in contact with the sole of the foot is the upward view. Figure 1It is a bottom view of the left sole. The sole is provided with a midsole body 10, a sliding member 1 and a driving member 2. The sliding member 1 is placed in the midsole body 10 and extends in the front-to-back direction. The front-to-back direction is a direction identification based on the orientation of the sole, and the orientation from the front toe of the sole to the rear heel is the front-to-back direction. When the shoe is in use, it is mainly bent at the forefoot portion, and the bending stiffness of the sole mainly depends on the bending stiffness of this part. The sliding member 1 extends in the front-to-back direction. When the sliding member 1 is located at the forefoot portion of the midsole body 10, the midsole body 10 bends and drives the sliding member 1 to bend. The sliding member 1 is made of carbon fiber material, which has high rigidity. At this time, the bending of the midsole body 10 drives the sliding member 1 to bend, which increases the bending stiffness of the midsole body 10, thereby increasing the bending stiffness of the sole. The driving member 2 drives the sliding member 1 to slide relative to the midsole body 10 in the front-to-back direction to adjust the bending stiffness of the sole. If the sliding member 1 cannot slide in the front-to-back direction and can only be fixed on the forefoot portion of the midsole body 10, then although the sliding member 1 increases the bending stiffness of the midsole body 10, the bending stiffness of the midsole body 10 cannot be adjusted. The driving member 2 drives the sliding member 1 to slide relative to the midsole body 10 in the front-to-back direction. When the sliding member 1 slides forward to the forefoot portion of the midsole body 10, the bending stiffness of the sole increases; when the sliding member 1 slides backward to the forefoot portion that is not located in the midsole body 10, the bending stiffness of the sole decreases. In this embodiment, the sliding member 1 increases the bending stiffness of the sole when it slides forward, and decreases the bending stiffness of the sole when the sliding member 1 slides backward. By changing the relative position of the sliding member 1 relative to the midsole body 10 in the front-to-back direction by the driving member 2, the bending stiffness of the sole can be adjusted, and the operation method of adjusting the bending stiffness of the sole is also simplified.
[0040] The controller 100 is placed on the hand and includes a stretch sensor 110 and a signal generator 120. The stretch sensor 110 is used to sense the stretching or contraction of the finger skin, and control the driving member 2 to drive the sliding member 1 to slide forward or backward through the signal generator 120. The above-mentioned "forward" and "backward" are direction identification based on the direction of the sole of the foot. The direction from the front toe of the sole to the rear heel is the front-to-back direction. Sliding toward the front toe is sliding forward, and sliding toward the rear heel is sliding backward. When the fingers move, the relative positions between the finger skins are displaced, which is specifically manifested as the stretching or contraction of the skin. The stretch sensor 110 is attached to the finger skin. When the finger skin stretches, the stretch sensor 110 attached to its surface is stretched, and when the finger skin contracts, the stretch sensor 110 attached to its surface is contracted. In this embodiment, the stretch sensor 110 is a resistive stretch sensor, and its resistance value changes according to its deformation of stretching or contraction. When the stretch sensor 110 stretches, its resistance value increases; when the stretch sensor 110 contracts, its resistance value decreases. The resistive stretch sensor 110 is a prior art. The principle that its resistance value increases when stretched and decreases when contracted is not described in detail here. The controller 100 compares the resistance value of the stretch sensor 110 with the resistance threshold, and controls the driving member 2 to drive the sliding member 1 to slide forward or backward through the signal generator 120 according to the comparison result. In this embodiment, the relative position of the sliding member 1 in the midsole body 10 along the front-to-back direction is controlled by the stretch sensor 110 to adjust the bending stiffness of the sole, and the user experience is improved through an intelligent adjustment method.
[0041] In this embodiment, the stretch sensor 110 is attached to the finger skin of the back of the hand along the finger extension direction. When the wearer makes a fist, the bending action of the fingers drives the finger skin of the back of the hand to stretch, and the stretching of the finger skin drives the stretch sensor 110 attached to its surface to stretch, so that its resistance value increases. When the resistance value of the stretch sensor 110 is greater than or equal to the stretch threshold, the signal generator 120 controls the driver 2 to drive the slider 1 to slide forward to increase the bending stiffness of the sole. When the wearer straightens the finger, the contraction of the finger skin drives the stretch sensor 110 attached to its surface to contract, so that its resistance value decreases. When the resistance value of the stretch sensor 110 is less than the contraction threshold, the signal generator 120 controls the driver 2 to drive the slider 1 to slide backward to reduce the bending stiffness of the sole. When the stretch threshold is greater than the contraction threshold, the resistance value of the stretch sensor 110 is greater than or equal to the contraction threshold, and when it is less than the stretch threshold, the controller does not control the driver 2. When you make a fist and bend your fingers, the bending stiffness of the sole increases; when you straighten your fingers, the bending stiffness of the sole decreases, which is in line with the user's usage scenario. Making a fist represents passion, so the sole needs to increase the bending stiffness to enhance the user's explosive power; straightening your fingers represents calmness, so the sole needs to reduce the bending stiffness to provide comfort.
[0042] In this embodiment, there are four stretch sensors 110, corresponding to the index finger, middle finger, ring finger and little finger, respectively, and attached to the finger skin of the back of the hand along the extension direction of each finger. When making a fist, the four fingers are bent at the same time. When the resistance values of the four stretch sensors 110 are simultaneously greater than the stretching threshold, the signal generator 120 controls the driver 2 to drive the slider 1 to slide forward to increase the bending stiffness of the sole. The four fingers are straightened at the same time. When the resistance values of the four stretch sensors 110 are simultaneously less than the contraction threshold, the signal generator 120 controls the driver 2 to drive the slider 1 to slide backward to reduce the bending stiffness of the sole. The use of four sensors 110 can better match the fisting action and the relaxation action. The controller 100 compares the resistance values of the four stretch sensors 110 at the same time. When the four resistance values are simultaneously greater than or equal to the stretching threshold or simultaneously less than the contraction threshold, the controller 100 controls the driver 2 to drive the slider 1 to slide in the front-to-back direction, so as to avoid the user from triggering the control system by mistake and improve the accuracy of the operation. In other embodiments, other numbers of stretch sensors 110 can also be used to design different triggering methods. The stretch sensor 110 can also be attached to other parts of the body, and the stretch sensor 110 is stretched or contracted by the stretching or contraction of the skin of other parts, and the driving member 2 is controlled to drive the sliding member 1 to slide forward or backward. In other embodiments, the controller 100 can be placed on the wearable object, and the stretch sensor 110 is used to sense the stretching or contraction of the wearable object. When the user uses the wearable object, it will cause the wearable object to stretch or contract, and change the resistance value of the stretch sensor 110. The controller 100 controls the driving member 2 to drive the sliding member 1 to slide in the front-to-back direction according to the comparison of the resistance value of the stretch sensor 110 with the stretch threshold or the contraction threshold, and adjusts the bending stiffness of the sole. In this embodiment, the controller 100 does not need to directly contact the skin, which improves the comfort and convenience of the user compared to attaching the sensor 110 to the user's skin.
[0043] As a preferred embodiment, the driving member 2 is a motor, which drives the sliding member 1 to slide forward to increase the bending stiffness of the sole or slide backward to reduce the bending stiffness of the sole by correspondingly rotating forward or reversely. The driving member 2 also includes a hard shell, and the motor is accommodated in the hard shell. The arch portion of the midsole body 10 is provided with a groove, and the hard shell of the driving member is accommodated in the groove and fixed to the midsole body 10. The driving member 2 also includes a battery, a Bluetooth module, etc. The driving member 2 is a bidirectional motor, and the motor can rotate forward or reversely. The signal generator 120 controls the motor to rotate forward or reversely according to the comparison result between the resistance value of the stretching sensor 110 and the threshold value. By controlling the motor to rotate forward or reversely, the sliding member 1 is driven to slide forward or backward, and the bending stiffness of the sole is intelligently adjusted.
[0044] In this embodiment, the midsole body 10 is provided with a slide groove 3 extending in the front-to-back direction, and the sliding member 1 slides in the slide groove 3 in the front-to-back direction. The slide groove 3 provides a channel for the sliding of the sliding member 1, so that the sliding member 1 can slide more smoothly. The midsole body 10 is also provided with a cable 4, which connects the two ends of the sliding member 1 and extends out of the slide groove 3 to connect with the driving member 2. The driving member 2 drives the sliding member 1 to slide in the slide groove 3 in the front-to-back direction by retracting and releasing the cable 4. When the driving member 2 rotates forward, the cable 4 at the front end of the sliding member 1 is pulled and the cable 4 at the rear end of the sliding member 1 is released, and the sliding member 1 is driven to slide forward; when the driving member 2 is reversed, the cable 4 at the rear end of the sliding member 1 is pulled and the cable 4 at the front end of the sliding member 1 is released, and the sliding member 1 is driven to slide backward. Preferably, the midsole body 10 is provided with four slide grooves 3 arranged in the left-right direction, and the sliding member 1 is provided in each of the four slide grooves 3. There are also four cables 4 respectively connected to the two ends of the corresponding sliding member 1 and extend out of the slide groove 3, and are all connected to the driving member 2. When the driving member 2 rotates forward, it pulls the cables 4 at the front ends of the four sliding members 1 at the same time, and releases the cables 4 at the rear ends of the four sliding members 1 at the same time, driving the four sliding members 1 to slide forward at the same time, thereby enhancing the bending stiffness of the sole; when the driving member 2 rotates reversely, it pulls the cables 4 at the rear ends of the four sliding members 1 at the same time, and releases the cables 4 at the front ends of the four sliding members 1 at the same time, driving the four sliding members 1 to slide backward at the same time, thereby reducing the bending stiffness of the sole. In other embodiments, the midsole body 10 is further provided with a conduit, which is accommodated in the slide groove 3 and fixed to the midsole body 10, and the sliding member 1 slides in the conduit along the front-to-back direction. The rigidity of the sliding member 1 is greater than that of the midsole body 10, and its sliding in the slide groove 3 will damage the midsole body 10. The sliding member 1 slides in the conduit so that it does not directly contact the midsole body 10, so that the midsole body 10 is not easily damaged, thereby improving the stability of the overall operation.
[0045] In addition, the present invention also provides a shoe, which comprises the control system for adjusting the bending stiffness of the sole.
[0046] The present invention provides a control system for adjusting the bending stiffness of a sole, wherein a sliding member 1 is used to increase the bending stiffness of the sole, and the sliding member 1 extends in the front-to-back direction, and is driven by a driving member 2 to slide in the front-to-back direction relative to a midsole body 10 in the front-to-back direction to adjust the bending stiffness of the sole. The sliding member 1 is usually made of carbon fiber material, which can improve the stiffness of the sole and provide a boosting performance for the user when the sliding member 1 recovers from deformation. When the sliding member 1 is located at the forefoot portion of the midsole body 10, the bending of the midsole body 10 drives the sliding member 1 to bend. The rigidity of the sliding member 1 is greater than that of the midsole body 10, and when the sliding member 1 is bent together with the midsole body 10, the bending stiffness of the midsole body 10 is increased, thereby increasing the bending stiffness of the sole. The driving member 2 is a motor, and the sliding member 1 is driven to slide in the front-to-back direction by the forward or reverse rotation of the motor. The driving member 2 adjusts the sliding member 1 to different positions of the midsole body 10 in the front-to-back direction to adjust the bending stiffness of the sole. When the slider 1 is located at the forefoot portion of the midsole body 10, the bending stiffness of the sole increases; when the slider 1 is not located at the forefoot portion of the midsole body 10, the bending stiffness of the sole decreases. The controller 100 is placed on the hand, and includes a stretch sensor 110 and a signal generator 120. The stretch sensor 100 is attached to the finger skin on the back of the hand to sense the stretching or contraction of the finger skin. The stretch sensor 110 is a resistive stretch sensor, and its resistance value changes with the deformation of stretching or contraction. Its resistance value increases when stretched, and its resistance value decreases when contracted. The four stretch sensors 110 are attached to the back skin of the index finger, middle finger, ring finger, and little finger along the finger extension direction. The four stretch sensors 110 can more accurately determine the finger movements and reflect the actual needs of the user. When the hand makes a fist, the skin on the back of the finger stretches, driving the four stretch sensors 110 to stretch, and the resistance values of the four stretch sensors 110 increase. When the resistance values of the four stretch sensors 110 are simultaneously greater than or equal to the stretch threshold, the signal generator 120 controls the driving member 2 to drive the four sliding members 1 to slide forward at the same time, thereby increasing the bending stiffness of the sole. When the hand straightens the finger, the skin on the back of the finger contracts, driving the four stretch sensors 110 to contract, and the resistance values of the four stretch sensors 110 decrease. When the resistance values of the four stretch sensors 110 are simultaneously less than the contraction threshold, the signal generator 120 controls the driving member 2 to drive the four sliding members 1 to slide backward at the same time, thereby reducing the bending stiffness of the sole.
